Travel Dates 2026-2027

This calendar is intended to aid parents and guardians with travel plans for the year ahead.  Please pay close attention to departure times.  We carefully plan and provide shuttle service so as not to conflict with school commitments.  If you schedule your own transportation, please respect all school commitments for your child.  Should airline travel require it, boarding students are permitted to remain on campus Friday evening of each of the school vacations.  A complete academic schedule will be posted in the spring. Please call (413) 529-3266 or email deanofstudents@williston.com with any questions.
